SPECIFICATION forming art of Letters Patent No. 756,592, dated April 5, 1904.

' Application filed November 11, 1903. Seria1 No.l80, 763. Norm lei.)

T on whom it may concern;

Be it known that I, JEAN BAPTISTE DAUDE; LIN," a citizen of the United States, residing at Fall River, in the county of; Bristol and Commonwealth of Massachusettahave invented certain new and usefulllmprovements in Self-Threading Shuttles, of which the following is a specification.

This invention relates to shuttles, and par ticularly to that class known as self-threading shuttles, in which the thread is brought into the threading-eye through a passage so arranged as to prevent its subsequent escape therefrom.

It is the object of the present invention to provide a shuttle which will be light, well balanced, cheap, strong, and durable; and to this end I have dispensed with the cumbersome and expensive plates heretofore commonly in use and attain my purpose by a simple arrangement of the delivery-eye and threading-slots relative to the shuttle, which will be more fully described in the following specification.

In the drawings, in which like letters of reference indicate corresponding parts throughout, Figure 1 is a side view of my shuttle; Fig. 2, a plan view of the delivery end of my shuttle; Fig. 3, a section on the line 3 3, Fig. 2; Fig. 4, a diagonal section along the line 4 4:, Fig. 2; and Fig. 5, a view of the threading-bushing removed.

A is a shuttle-body of any usual type, having a spindle-recess a and a threading-recess C.

D is a delivery-eye, in which is located a delivery-bushing E, having an opening E, connecting with a slot E F is a threading-slit leading from the upper face of the shuttle-body into the delivery-eye and connecting with the slit E in the bushing.

The delivery-eye D pierces the sh uttle-body transversely and is directed slightly downward, emerging at the side of the shuttle partially behind a shoulder G on the shuttlebody. The slit E is on the lower side of the bushing and at its end lies behind the shoulder G, which is disposed across the lower side of the delivery-eye.

H is a cleared portion on the delivery end of the shuttle, being sufiicientlyr educed to be out of contactwith any part of the loom in its path. The threading-slit]? isicutlthrough this cleared portion, so that'theedges of the slit arenot exposed to wear, andv consequently do not; b come o gheneduandurs uir t constant sandpapering that is necessary to keep the ordinary shuttle in condition when the edges of its slits become worn and splintered.

In threading the shuttle the thread T is first drawn forward through the threadingrecess 0 and into the slit F under the nose Nformed thereby until the thread passes over the opposite nose N. Then by the rearward motion of the thread it is drawn under said last named nose and through the opening E and the slit E into the delivery-eye. As it passes into the outer end of the deliveryeye the thread is bent to pass over the shoulder G, which lies across theend of the delivery-eye, so that when it at last clears itself of the slit and rises into the delivery-eye it is raised by this shoulder G above the plane of the slit by which it entered. The level of this shoulder G is clearly shown in the sections in Figs. 3 and i and is indicated by the dotted line G G in Fig. 5.

The direction of the delivery-eye and the location and nature of the threading-slits may of course be varied, and various other modifications may be made without departing from the spirit of my invention.

What I therefore claim, and desire to secure by Letters Patent, is

1. The combination with a shuttle having a delivery-eye, said eye having a portion of the shuttle-body remaining across its outer end,

a bushing located in said delivery-eye, threadthe eye to prevent the escape of the thread therefrom.

2. The combination in a shuttle having a delivery-eye, of a shoulder on the shuttle-body disposed across said eye to prevent the escape of the thread therefrom, a threading-passage permitting the thread to be drawn into the delivery-eye, said passage entering said eye be.- low the plane of said shoulder.

3. The combination of a shuttle having a delivery-eye, said eye being partially closed at its mouth by a portion of the shuttle-body and a threading-passage entering said threading-eye behind said closure.

L. The combination with a shuttle having a delivery-eye and a threading-passage leading thereto said delivery-eye emerging partially behind a shoulder on the shuttle-body, and a bushing in said delivery-eye having a slit behind said shoulder to prevent the escape of the thread from the bushing.

5. The combination with a shuttle having a delivery-eye, a shoulder on the shuttle-body, said delivery-eye emerging partially behind said shoulder and a threading-passage below the plane of said shoulder permitting the thread to be drawn into the delivery-eye.

6. The combination of a shuttle having a delivery-eye, disposed at an angle to the stirface of the shuttle, said eye being only partially cut through at said surface to leave a shoulder on the shuttle-body and a threadingpassage entering said threading-eye behind said shoulder.

7 The combination with a shuttle-body having a delivery-eye of a cleared portion Whose surface is lower than that of the surrounding shuttle-body and protected thereby from contact, a threading-passage permitting the thread to be drawn into the delivery-eye, said threading-passage intersecting said shuttle at said cleared surface.

In testimony whereof I aflix my signature in presence of two witnesses.
